php多層數組和對象的轉換

　　多層數組和對象轉化的用途很簡單，便於處理WebService中多層數組和對象的轉化

　　簡單的(array)和(object)只能處理單層的資料，對於多層的數組和對象轉換則無能為力。

　　通過json_decode(json_encode($object)可以將對象一次性轉換為數組，但是object中遇到非utf-8編碼的非ascii字元則會出現問題，比如gbk的中文，何況json_encode和decode的效能也值得疑慮。

　　下面上代碼：

<?php function objectToArray($d) {if (is_object($d)) {// Gets the properties of the given object// with get_object_vars function$d = get_object_vars($d);} if (is_array($d)) {/** Return array converted to object* Using __FUNCTION__ (Magic constant)* for recursive call*/return array_map(__FUNCTION__, $d);}else {// Return arrayreturn $d;}} function arrayToObject($d) {if (is_array($d)) {/** Return array converted to object* Using __FUNCTION__ (Magic constant)* for recursive call*/return (object) array_map(__FUNCTION__, $d);}else {// Return objectreturn $d;}}// Useage:// Create new stdClass Object         $init = new stdClass;// Add some test data$init->foo = "Test data";$init->bar = new stdClass;$init->bar->baaz = "Testing";$init->bar->fooz = new stdClass;$init->bar->fooz->baz = "Testing again";$init->foox = "Just test"; // Convert array to object and then object back to array$array = objectToArray($init);$object = arrayToObject($array); // Print objects and arrayprint_r($init);echo "\n";print_r($array);echo "\n";print_r($object);?>
